I was about to make my own plugin when I found this one, I soon saw that I didn't need to create one anymore, your plugin is amazing but I missed a Wireless Remote... that I ended up programming one later because I really needed it kkkkk congratulations on the plugin. (Sorry for the translations)

@FentisDev If you wanted to, you could make a pr adding that wireless remote. I'll take a look at the bug

To Reproduce
Create a system and place any item via Hopper and restart the server.

Would I restart the server when the hopper is emptying, or when the hopper is empty?

[FentisDev]

The hopper puts an item into the system and then you restart it, yes it is empty at the time it restarts.
